Question

a manufacturer inspects 800 personal video players and finds that 798 of them have no defects. what is the experimental probability that a video player chosen at random has no defects? express your answer as a percent.

Answer 1

`Given:\\Number \; of \; Video \; Players \; with \; no \; de\dot{f}ect=798\\Total \; Number \; of \; video \; Players = 800`
`Let \; A \; be \; an \; Event \; that \; a \; video \; player \; chosen \\\; at \; random \; has \; no \; de\dot{f}ect\\P(A) \; be \; the \; experimental \; probability\\ of \; event \; A \; to \; happen.\\\\The \; formula \; is \; below:\\P(A) \; = \;  \frac{Number \; of \; video \; players \; with \; no \; de\dot{f}ects }{Total \; number \; of \; video \; players}\\\\P(A)=798 / 800 =0.9975=99.75 \%`
